1.0 PURPOSE AND SCOPE 1.1 PURPOSE Work in confined spaces can present a significant risk for workers performing such work when appropriate precautions are not taken. To protect workers entering, working in or working near confined spaces, the University requires that such work is performed following very stringent procedures. To support this, the University has a Confined Spaces Policy and has established a Confined Spaces Management Program. Under the authority of the Policy, the University s Confined Spaces Management Program establishes a comprehensive system to actively manage and rigorously control all work done in confined spaces. The program is written in accordance with the requirements of Ontario Regulation 632/05, Confined Spaces made under the Occupational Health and Safety Act of Ontario and the Ministry of Labour s Confined Spaces Guideline. 1.2 SCOPE The Confined Spaces Management Policy applies to all confined spaces in buildings/ structures/properties owned or leased by the University of Guelph, to all faculty, staff and students of the University, and University of Guelph workers and maintenance contractors who enter or work in a confined space. The Confined Spaces Management Program does not apply to work in confined spaces that are under the jurisdiction of a constructor. 1.3 PROGRAM ELEMENTS The major elements of the Confined Spaces Management Program are: 1) documentation and communication of roles and responsibilities; 2) written record identifying all confined spaces (types and locations) and confined space supervisors for University buildings/structures/properties; 3) identification and assessment of health and safety hazards in each confined space; 4) written plan for the control or elimination of hazards identified in the assessment; 5) provision of an entry permit system; 6) provision of appropriate training to University of Guelph workers and information to maintenance contractors who enter and/or work in confined spaces; 7) control of access to confined spaces; 8) provision of a co-ordination document for confined spaces with multi-employer involvement; 9) maintenance work by University of Guelph workers in confined spaces; 10) maintenance contract work in confined spaces; 11) provision of an attendant and and written on-site rescue procedures for confined spaces; 12) atmospheric testing of confined spaces; 13) program audit and review.

2.0 REGULATORY REQUIREMENTS The confined spaces management program is written in accordance with the requirements of Ontario Regulation 632/05, Confined Spaces made under the Occupational Health and Safety Act of Ontario and the Ministry of Labour s Confined Spaces Guideline, which can be found at: http://www.e-laws.gov.on.ca/dblaws/regs/english/050632_e.htm and http://www.labour.gov.on.ca/english/hs/guidelines/confined/index.html CONFINED SPACES MANAGEMENT PROGRAM Page 5 of 45

3.0 BACKGROUND AND GLOSSARY 3.1 BACKGROUND A confined space is defined as a fully or partially enclosed space, (a) that is not both designed and constructed for continuous human occupancy, and (b) in which atmospheric hazards may occur because of its construction, location or contents or because of work that is done in it. Confined spaces may include: storage tanks, process vessels, boilers, water towers, silos, sewer lines, utility service chambers and open top spaces such as pits and tubs. Confined space accidents do not happen very often, but when they do, they are quite often fatal. Confined spaces vary widely in their physical characteristics (size and shape) and in the reasons for which they are entered. Some typical reasons for entering a confined space include: inspection and maintenance of equipment and machinery checking and reading meters, gauges, dials, charts and other indicators repair work, including welding operations maintenance activities such as abrasive blasting or application of paints or other coatings installing, inspecting, repairing and replacing valves, piping, pumps, motors, etc. in underground vaults and pits cleaning activities to remove sludge and other waste materials installing, splicing, repairing, and inspecting electric, telephone and fibre optic cables Activities which seem safe when conducted in an open space can become quite hazardous when performed in a confined space. The hazards in confined spaces may be broadly divided into two categories: atmospheric hazards and physical hazards. The three general classes of atmospheric hazards include: oxygen-deficiency or oxygen-enrichment accumulation of flammable, combustible or explosive agents accumulation of toxic atmospheric contaminants, including gases, vapours, fumes, dusts or mists As per the definition of a confined space (above), the only class of hazard that determines its classification as a confined space is an atmospheric hazard; it is necessary, however, to perform an assessment of the physical hazards in a confined space because many of these hazards do exist in confined spaces and are exacerbated by the physical nature of the space (generally, enclosed and not constructed for continuous human occupancy). Physical hazards, include: mechanical and electrical: the unexpected movement of mechanical equipment or the unexpected discharge of electrical equipment in a confined space presents a very hazardous situation for anyone within the space. general safety: means of access and egress, temperature extremes, poor visibility, noise, slips, trips, falls, falling objects, exposure to pathogens, etc. engulfment: the movement or shifting of material within a confined space has been responsible for many injuries and fatalities. Silos with grain inside are a prime example of this type of hazard. CONFINED SPACES MANAGEMENT PROGRAM Page 6 of 45

3.2 GLOSSARY Atmospheric Hazards Atmospheric Testing Attendant Confined Space Confined Space Supervisor Cold Work Competent Person Co-ordination Document Engulfment mean (a) the accumulation of flammable, combustible or explosive agents, (b) an oxygen content in the atmosphere that is less than 19.5 per cent or more than 23 per cent by volume, or (c) the accumulation of atmospheric contaminants, including gases, vapours, fumes, dusts or mists, that could, (i) result in acute health effects that pose an immediate threat to life, or (ii) interfere with a person s ability to escape unaided from a confined space; pre-entry testing by a competent person with a calibrated directreading instrument to measure (in sequence) oxygen content, flammable gases and vapours, and toxic air contaminants. Because contaminants can stratify at different levels, the entire confined space must be evaluated remotely. If the measurements indicate that the atmosphere is within acceptable limits, the entry may proceed. If not, additional ventilation or respiratory protective equipment must be provided, or entry is prohibited. A worker who is trained in the hazards of confined spaces and whose primary responsibility is to monitor and assist the workers in the confined space. means a fully or partially enclosed space, (a) that is not both designed and constructed for continuous human occupancy, and (b) in which atmospheric hazards may occur because of its construction, location or contents or because of work that is done in it A supervisor who has principal authority or charge of the confined space means work that is not capable of producing a source of ignition a person qualified to evaluate confined space hazards, perform atmospheric tests and/or evaluate the results. A person familiar with OHS Act and Regulation 632/05 Confined Spaces. A document prepared by the lead employer that coordinates the work of more than one employer in a confined space to protect the health and safety of all workers The surrounding and effective capture of a person by liquid or finely divided solid that can be aspirated to cause death by filling or plugging the respiratory system, or that can exert enough force on the body to cause death by strangulation, constriction or CONFINED SPACES MANAGEMENT PROGRAM Page 7 of 45

5.0 CONFINED SPACE IDENTIFICATION AND INVENTORY 5.1 Identification 5.1.1 Every confined space in buildings/structures/properties owned or leased by the University of Guelph shall be in the charge of a confined space supervisor. 5.1.2 All confined spaces in buildings/structures/properties owned or leased by the University of Guelph shall be identified and provided with an identification number. 5.1.3 The confined space supervisor is responsible for the identification of all confined spaces under his/her jurisdiction. 5.1.4 Once the confined space has been identified, it must be properly signed to bear the unique identification number for the confined space. The identification number is comprised of four parts: building/structure/property number type room number number: Building/structure/property number is a unique identifier for the building/ structure/property (e.g. Alumni House -- building # 66) Group/Type of confined space (see Table 1 on the next page -- e.g. sewer pits have been classified in group A ) Room number is the number of the room in which the confined space is located; if there is no room number associated with its location, identify as 000 on the Campus Number is a unique identifier at that location (e.g. spaces are numbered consecutively -- i.e. 01, 02, 03, etc.). An example of a typical confined space identification number is: 66-A-012-01. 5.1.5 The confined space supervisor is responsible for the installation of identification numbers on all confined spaces under his/her jurisdiction (see Section 10.0 -- Access Control). Note: In some circumstances, the use of signs may not be practical, such as for service chambers and grates. A tool is usually required for removal of the cover, and therefore, it would likely be considered secure against entry. 5.2 Inventory ` 5.2.1 All confined spaces in buildings/structures/properties owned or leased by the University of Guelph shall be inventoried through a survey process. This survey provides the data for the inventory of confined spaces. 5.2.2 The survey/inventory shall include: Building/structure/property in which the confined space is located Name of the person conducting the inventory Date of the inventory Name of the confined space Name of the confined space supervisor Type of confined space Location of the confined space CONFINED SPACES MANAGEMENT PROGRAM Page 14 of 45

Location of access points Confined space identification number Comments (any other information deemed useful to the inventory) 5.2.3 Confined spaces will be inventoried using the form provided in Appendix A. 5.2.4 The confined space supervisor is responsible for providing confined space inventories for buildings/structures/properties under his/her jurisdiction. 5.2.5 Confined space inventories shall be readily accessible to all authorized personnel. 5.3 Updating Inventories 5.3.1 The initial confined space inventories will be updated as a result of new or reconfigured confined spaces as well as decommissioned confined spaces. 5.3.2 The confined space supervisor is responsible for maintaining the confined space inventories for confined spaces under his/her jurisdiction. 5.3.3 The inventory shall be updated at the time of commissioning or decommissioning the confined space. 5.3.4 The updated written record (inventory) shall be filed with the pertinent confined space supervisor and copied to the Industrial - Agricultural Safety Officer (Environmental Health and Safety) at the time of commissioning or decommissioning the confined space.

6.0 HAZARD ASSESSMENT In confined spaces, hazards may exist as a result of the design, construction, location, use or contents of the space; they may also develop during the work activity inside the confined space. These hazards may be atmospheric hazards and/or physical hazards. 6.0.1 Before any worker enters a confined space, the confined space supervisor or designate shall ensure that an adequate assessment of the hazards related to the confined space has been carried out. The form in Appendix B shall be used to provide the hazard assessment. 6.0.2 The confined space supervisor or designate shall appoint a person with adequate knowledge, training and experience to be able to perform the hazard assessment, and shall maintain a record containing details of the person s knowledge, training and experience. 6.0.3 The hazard assessment shall be recorded in writing, signed and dated by the person who carries out the assessment, and provided to the confined space supervisor, prior to any worker entering a confined space. 6.0.4 The confined space supervisor or designate shall ensure that a hazard assessment is repeated each time a new entry permit is issued for work to be done in a confined space. New hazards may have developed since the last time the assessment was carried out. In addition, a different work activity could result in different hazards being introduced into the confined space. Note: an assessment is not needed each time a worker goes in and out of the confined space during the period to which an entry permit applies. 6.0.5 Where two or more confined spaces are similar in construction and have the same hazards, the assessment for each specific confined space may be recorded in a single document, however, it is important to clearly identify the specific confined space(s) to which each assessment applies. 6.0.6 The entry supervisor or designate shall ensure that the hazard assessment is incorporated into the entry permit and will be available to every worker who performs work to which the assessment relates. 6.0.7 The confined space supervisor shall retain records of the hazard assessment for the longer of the following periods: 1. One year after the document is created. 2. The period that is necessary to ensure that at least the two most recent records that relate to a particular confined space are retained. CONFINED SPACES MANAGEMENT PROGRAM Page 16 of 45

7.0 CONFINED SPACE PLAN The plan is a specific set of measures and procedures to control hazards identified by the assessment for that confined space to allow workers to enter and work in that space safely. The plan also includes provisions for on-site rescue procedures, rescue equipment and methods of communication. 7.0.1 Before any worker enters a confined space, the confined space supervisor or designate shall ensure that an adequate written plan has been developed, signed, dated and implemented by a competent person for the confined space. The form in Appendix C shall be used to provide the written plan. 7.0.2 The plan shall include provisions for: hazard identification and control the duties of workers; co-ordination (multi-employer involvement) attendants means of entry/exit personal protective equipment isolation of energy and control of materials movement ventilation and purging procedures for working in the presence of explosive or flammable substances atmospheric testing on-site rescue -- procedures, equipment and method of communication 7.0.3 The confined space supervisor or designate shall ensure that a written plan is repeated each time a new entry permit is issued for work to be done in a confined space. New hazards may have developed since the last time the plan was written. In addition, a different work activity could result in different hazards being introduced into the confined space. Note: a written plan is not needed each time a worker goes in and out of the confined space during the period to which an entry permit applies. 7.0.4 Where two or more confined spaces are similar in construction and have the same hazards as identified by the assessment for each specific confined space, the written plan may be recorded in a single document, however, it is important to clearly identify the specific confined space(s) to which each written plan applies. 7.0.5 The entry supervisor or designate shall ensure that the written plan is incorporated into the entry permit and will be available to every worker who performs work to which the plan relates. 7.0.6 The confined space supervisor shall retain records of the written plan for the longer of the following periods: 1. One year after the document is created. 2. The period that is necessary to ensure that at least the two most recent records that relate to a particular confined space are retained. CONFINED SPACES MANAGEMENT PROGRAM Page 17 of 45

8.0 ATTENDANT AND ON-SITE RESCUE 8.1 Attendant An attendant is a worker who is trained in the hazards of confined spaces and whose primary responsibility is to monitor the safety of the worker(s) and to provide assistance to the workers in the confined space. 8.1.1 Whenever a worker is to enter a confined space, the confined space supervisor or designate shall assign an attendant. 8.1.2 The attendant shall not enter the confined space and has to be located outside and near the entrance of the confined space as determined by the hazard assessment and the resulting confined space plan. As well, he/she shall be in constant communication with the worker(s) inside the space via an adequate communication system and able to immediately summon a rescue response should it be required (see Appendix C). 8.2 On-site Rescue (see Appendix C) 8.2.1 Before a worker enters a confined space, the entry supervisor or designate shall ensure that adequate written on-site rescue procedures that apply to the confined space are available and are ready for immediate implementation, in accordance with the relevant plan. 8.2.2 Before a worker enters a confined space, the entry supervisor shall ensure that all emergency procedures, including procedures relating to emergencies outside the confined space are reviewed with all entrants and other related personnel. 8.2.3 Before a worker enters a confined space, the entry supervisor or designate shall ensure that an adequate number of appropriately trained persons are available for immediate implementation of the on-site rescue procedures that apply to the confined space. Appropriate training shall include: the on-site rescue procedures that apply to the confined space; first aid and cardio-pulmonary resuscitation; and the use of the rescue equipment required in accordance with the relevant plan 8.2.4 The entry supervisor or designate shall ensure that the rescue equipment identified in the relevant plan is: readily available to effect a rescue in the confined space; appropriate for entry into the confined space; and inspected and recorded in writing as often as is necessary to ensure it is in good working order, by a person with adequate knowledge, training and experience. CONFINED SPACES MANAGEMENT PROGRAM Page 18 of 45

9.0 ENTRY PERMIT SYSTEM Entry permits are documents which certify that an assessment of the confined space has been completed and that specific precautions such as isolation, protective equipment, ventilation and atmospheric testing are required before workers can enter the confined space. Entry permits are required for entry into all confined spaces. 9.0.1 Before any worker enters a confined space, the entry supervisor or designate shall ensure that a separate entry permit is issued each time work is to be performed in a confined space. The forms in Appendix D shall be used to provide the entry permit and the documenting of atmospheric testing. 9.0.2 The entry permit shall include provisions for: the location of the confined space a description of the work to be performed in the confined space a description of the hazards and the corresponding control measures the time period for which the entry permit applies the name of the attendant a record of each worker s entries and exits a list of equipment required for entry and rescue hot work (if any) and corresponding control measures 9.0.3 The entry supervisor or designate shall ensure that the hazard assessment and the written plan are incorporated into the entry permit and will be available and reviewed with all entrants and other related personnel prior to entry into the confined space. 9.0.4 The confined space supervisor shall retain records of the entry permit and atmospheric testing for the longer of the following periods: 1. One year after the document is created. 2. The period that is necessary to ensure that at least the two most recent records that relate to a particular confined space are retained. 10.0 ATMOSPHERIC TESTING OF CONFINED SPACES CONFINED SPACES MANAGEMENT PROGRAM Page 19 of 45

Atmospheric testing is required when the relevant assessment determines that the confined space may contain atmospheric hazards. The atmospheric hazards of concern include oxygen content outside the acceptable range of 19.5 to 23%, the potential accumulation of flammable, combustible, or explosive agents, or the accumulation of atmospheric contaminants. Atmospheric test results shall be recorded using the form provided in Appendix E. 10.0.1 The entry supervisor or designate shall ensure that testing is conducted by a person with adequate knowledge, training and experience to perform adequate tests. Testing is required to ensure that acceptable atmospheric levels are maintained in the confined space in accordance with the relevant plan. 10.0.2 The person performing the tests shall use calibrated instruments that are in good working order and are appropriate for the hazards identified in the relevant assessment. The tests shall be performed in a manner that does not endanger the health and safety of the person performing them. 10.0.3 The entry supervisor or designate shall ensure that the testing is performed using continuous monitoring and that the test results are recorded at adequate intervals as determined by the confined space plan. 10.0.4 The atmospheric test results form shall include provisions for: the location of the confined space the name of the atmospheric tester the make/type/serial number of the sampling instrument the calibration method and the date last calibrated continual sampling and the planned recording intervals results obtained in atmospheric testing 10.0.5 The confined space supervisor shall retain records of testing for the longer of the following periods: 1. One year after the document is created. 2. The period that is necessary to ensure that at least the two most recent records that relate to a particular confined space are retained.
